Dark Mode is a free Chrome extension designed to enhance your browsing experience by reversing light colors to dark and dark text to light. This experimental tool works by scanning a webpage's CSS for light and dark color elements and inverting their lightness, making it easier on the eyes, especially in low-light environments. Users can enjoy a more comfortable viewing experience while reading or browsing online content.

While Dark Mode is effective for most webpages, it may encounter limitations on sites that restrict the use of external CSS due to CORS policies. This means that on certain pages, the extension may not function as intended. Overall, Dark Mode is a valuable addition for users looking to reduce eye strain and improve their web experience.
